Legion Go S powered by SteamOS review: A purpose-built OS makes all the difference
Earlier this year, Lenovo released a more streamlined and potentially affordable take on its flagship gaming handheld in the Legion Go S. Unfortunately, the Windows 11 version came first, which wasn’t the one we were most excited about. Now, the Legion Go S powered by SteamOS has arrived, and oh my, what a difference an operating system can make. Not only does this model feature a UI that's much better suited for a portable gaming machine, it has faster performance as well. But the best part is that the SteamOS variant is less expensive than its Windows sibling. All of this makes for a handheld that's a welcome alternative to the Steam Deck, especially for anyone who's not a fan of Valve's hardware.
Design and display: Keeping it simple
Like its sibling, the SteamOS version of the Legion Go S features a very straightforward design. A big difference between the two is that this model features a dark purple body instead of the white shell on the Windows variant. Thanks to its large 8-inch 1200p display and sizable grips, it's a bit chunkier than rivals like the Steam Deck or the ROG Ally X. At 500 nits, brightness is above average compared to typical handheld PCs. However, because Lenovo uses an LCD panel, colors aren't quite as vibrant and you don't get those pure inky blacks like you do on a system with an OLED screen such as the original Legion Go.
I like that Lenovo included Hall effect sensors for its joysticks, along with a toggle that lets you adjust the pull depth of the triggers. Plus, the addition of a second USB-C port allows you to charge the device while keeping other accessories plugged in. There's also a pair of programmable paddles on the back and a handy microSD card slot for expandable storage.
The biggest departures from the flagship Legion Go are that this model's joysticks and buttons cannot be detached and its built-in touchpad is significantly smaller. This means the latter is better suited to moving the cursor around SteamOS in desktop mode or to navigating menus than it is as a true alternate control scheme while playing games. You also don't get a fingerprint reader, which I think should be a standard inclusion on handheld gaming PCs at this point.
Performance and software: Better with SteamOS
The Legion Go S powered by SteamOS is available in multiple configurations. Our $830 review unit features an AMD Ryzen Z1 Extreme chip with 32GB of RAM and 1TB of storage. Unfortunately, this means I wasn't able to run true apples-to-apples performance tests with the Ryzen Z2 Go-equipped version of the Windows Legion Go S I reviewed earlier this year. But given the lackluster results from that model, I generally wouldn't recommend any handheld powered by that chip, even though that version is significantly more affordable. If budget is a concern, Valve's Steam Deck remains the better option.
Even though the Go S with SteamOS features the exact same chip, I actually saw slightly better performance here compared to the original Legion Go. With both systems set to a 15-watt TDP (total device power), the Legion Go S edged out the Windows model in Cyberpunk 2077 at 800p on medium graphics by pumping out 58 fps versus 54 fps. By comparison, the Steam Deck OLED managed 53 fps. And in Control at 800p on medium, it was a similar situation, though the gap was even smaller. The Legion Go S hit 29 fps, beating out the OG Legion Go (27 fps) and the Steam Deck OLED (24 fps).
The cause of the SteamOS model's improved horsepower is hard to pinpoint — especially as performance varies from title to title — but it's generally due to Valve's platform having less overhead and system processes than Windows-based rivals. And if that wasn't enough, the SteamOS UI is better designed for a dedicated gaming machine, as turning on the system boots you right into your game library as opposed to spitting you out into Microsoft's classic desktop view. There are also some minor tweaks in Valve's OS to support features like the built-in RGB lighting on the Legion Go S — something the Steam Deck doesn't have.
For fans of SteamOS, the main reason aside from price to pick a Steam Deck over the Legion Go S (or vice versa) is that each system features different performance targets. Valve's handheld has a TDP that tops out at 15 watts, and at lower power levels, it features better energy efficiency than the Legion Go S. This makes it more suitable for people who regularly play older games or less demanding 2D fare. Alternatively, Lenovo's handheld has a max TDP of 33 watts (or 40 when plugged into the wall), which makes it more adept at handling resource-intensive modern titles. So if you want higher frame rates (which you probably do), a Z1 Extreme Legion Go S with SteamOS has way more headroom to push pixels even harder.
Battery life: Just a touch more efficient
Featuring a mid-size 55WHr battery, longevity on the Legion Go S when running SteamOS doesn't really stand out. However, I found that on average, it runs up to 30 minutes longer than its Windows counterpart across a number of titles. When playing Metal Slug Tactics, it lasted just shy of three hours (2:50) compared to closer to an hour and a half for the Windows 11 model (2:33). It was a similar situation in Elden Ring, where the SteamOS version was able to continue for an extra 15 minutes after its sibling conked out.
Wrap-up
The Legion Go S powered by SteamOS is a simple and well-built gaming handheld with an even bigger screen than Valve's portable and arguably better ergonomics. When configured with a Ryzen Z1 Extreme chip, it's a better choice for playing more demanding modern games without feeling forced to switch to a Windows-based device. It also has a more optimized UI than its Microsoft-powered rivals while retaining handy features like Hall effect joysticks and dual USB-C ports.
With Z1 Extreme models starting at $830 instead of $600 for the Z2 Go configs, though, it's not quite as affordable as I thought it would be back when it was first announced at the beginning of the year. But even so, it's nice to have options. And as just one of two handhelds on the market that come with SteamOS pre-installed, the Legion Go S makes an interesting argument as a bigger and more powerful upgrade to the Steam Deck.
